„Preferred settings on the 2WRCE“
Design, function and section: type 2WRC(E)
The valve types 2WRC(E) are 3-stage high response valves.
They control the rate and direction of a flow and are primarily
used in closed loop control circuits.
Design
They comprise of the following sub-assemblies:
– A pilot control valve (1) as a 2-stage servo directional valve
(pilot)
• With a dry torque motor
• Low friction jet / flapper amplifier and
• Mechanical feedback of the spool position
– A main control spool (2) for flow control
– An inductive position transducer (3) whose core (4) is
attached to the spool (2) of the third stage
– And integrated control electronics (5) for 2WRCE or
separate electronics for the 2WRC version.
Function
Within the integrated control electronics (OBE) the command
and actual values are compared and the pilot control valve
solenoids are controlled via a currrent proportional the closed
loop control deviation.
The pilot control valve asumes a proportional control position
and controls the flows into or from control chambers A (6) and
B (7), that actuate the main spool (2) by means of the closed
loop control valve until the system deviation is 0.
The stroke of the main spool is thus controlled in proportion
to the command value. It must be noted herethat the flow also
depends on the valve pressure drop.
Valve features
Flow can be passed through the valve from A to B or from B
to A.
The poppet spool closes or opens with a command value of
approx. 2 %. With smaller command values the valve‘s closed
loop control circuit trys to correct the spool position and there-
by presses the spool, with up to the full system pressure, onto
its seat and closes the connection leak-free.
The stated switching times are only valid for the closed loop
control range of the valve. With command value jumps from the
seat to small opening values, additional delay times occur.
The 2 % opening point (= 0.2 V) is factory pre-set. When
replacing the pilot control valve or control electronics the
opening point can be calibrated by adjusting the position
transducer (3) by using the 13A/F nut.
When carrying out an exchange no adjustments to the control
electronics and pilot control valve (= closed loop controller,
controller or control electronics), other than the zero calibration
at the position controller may be carried out.
Only the filter element can be replaced on the pilot control
valve (see data sheet „Servo directional valve“)
Due to the diameter differences in the seat area, the spools
are not pressure balanced. To compensate for the force
differences for spool „K001“ 6 %, and for spools „D001“ and
„S001“ 22 % of the system pressure is required as the control
pressure, and then by adding reserves for flow forces and
dynamics, the recommended minimum control pressure can be
obtained (see technical data).
13A/F

Preferably port B should be connected
to the actuator.

„Preferred setting on the 3WRCE“
Design, function and section: type 3WRC(E)
1)
The valve types 3WRC(E) are 3-stage 3-way high response
valves.
They control the rate and direction of a flow and are primarily
used in closed loop control circuits.
Design
They comprise of the following sub-assemblies:
– A pilot control valve (1) as a 2-stage servo directional valve
(pilot)
• With a dry torque motor
• Low friction jet / flapper amplifier and
• Mechanical feedback of the spool position
– A main control spool (2) for flow control
– An inductive position transducer (3) whose core (4) is
attached to the spool (2) of the third stage
– And integrated control electronics (5) for 3WRCE or
separate electronics for the 3WRC version.
Function
Within the integrated or external electronics, the command and
actual values are compared, and accordingly the associated
control deviation controls, the pilot valve torque motor via a
proportional current.
The pilot control valve assumes a proprtional control position
and controls the pilot control flows in/out of the control
chambers A (6) and B (7), that controls the main spool (2) via
the closed loop circuit until the control deviation is 0.
The stroke of the main spool is thereby closed loop cont-
rolled in proportion to the command value. It has, however to
be taken into account that the flow is also dependent on the
pressure drop.
Valve features
The 0 % opening point (L006 and V001 spools) is factory
pre-set. When replacing the pilot control valve or the control
electronics the opening point can be calibrated by adjusting
the position transducer (3) by using the 13A/F nut.
When carrying out an exchange no adjustments to the control
electronics and pilot control valve (= closed loop controller,
controller or control electronics) may be carried out other than
the zero calibration at the position controller.
Only the filter element can be replaced on the pilot control
valve (see data sheet „Servo directional valves“).
